Note:
STPM13/14: each current channel must be calibrated separately. In order to do this, follow
these steps:
Apply the nominal test voltage to the voltage sensor, and the nominal test current to the
primary current channel sensor. Do not apply such current on the secondary current
channel sensor.
Adjust the voltage and primary current calibrators (see above).
Disconnect the nominal test current from the primary current channel sensor, and apply it to
the secondary current channel sensor.
Adjust only the secondary current calibrators, so that the same power is computed.
